Guidelines
You can mount the router in a cabinet that contains a 19-in.
(48.3 cm) rack as defined in Cabinets, Racks, Panels, and
Associated Equipment (document number EIA-310–D)
published by the Electronics Industry Association
( http://www.eia.org ).
NOTE: The rack must meet the strength requirements to
support the weight of the router.
The minimum cabinet size must be able to accommodate
the maximum external dimensions of the router.
The outer edges of the mounting brackets extend the width
of the chassis to 19 in. (48.3 cm).
The minimum total clearance inside the cabinet is 30 in.
(76.2 cm) between the inside of the front door and the inside
of the rear door.
When you mount the router in a cabinet, ensure that ventilation
through the cabinet is sufficient to prevent overheating.
Ensure an adequate cool air supply to dissipate the thermal
output of the router or routers.
Ensure that the cabinet allows the hot exhaust air from the
chassis to exit the cabinet without recirculating into the
router. An open cabinet (without a top or doors) that
employs hot air exhaust extraction from the top allows the
best airflow through the chassis. If the cabinet contains a
top or doors, perforations in these elements assist with
removing the hot air exhaust.
Install the router in the cabinet in a way that maximizes the
open space on the side of the chassis that has the hot air
exhaust. This space maximizes the clearance for critical
airflow.
Route and dress all cables to minimize the blockage of
airflow to and from the chassis.
Ensure that the spacing of rails and adjacent cabinets allows
for proper clearance around the router and cabinet.
A cabinet larger than the minimum required provides better
airflow and reduces the chance of overheating.
